Very interesting! I'd think it would be a bug if it did work that way.

Jim,
Thanks for sharing all your hard work. Have you
PHP, at least php 3.x, has a series of fuctions like
is_string, is_integer, is_array etc. I know they're
there...I don't us them so I don't know exactly
where...this might be what you're looking for...

i need to find it as an integer or real or float for the sql. which by the
way is MySQL.
thank you for responding, but I already know that gettype and all the other

How about a regex check for numeric characters with and without a decimal

I would right a function that would return a result and try an match within
the different types.
if (isdate($a))
{
Dtype = date;
}
if (isdigit($a))
{
Dtype = int;
}
return (Dtype);
etc..

hello all,
let's say i have this:
$a="varone=hello world|vartwo=2.44|varthree=100|";
now i do this:
$b=explode('|',$a);
$z=count($b);
for ($x=0;$x$z;$x++) {
$tmp=explode('=',$b[$x]);
and i want to find out if $tmp[1] is a string or an integer (that's really
all I need to determine
